As we know, WiMAX make us simply to connect to everyone through the internet either inside or outside home. There are several uses of WiMAX but the bandwidth and reach of WiMAX have to make it suitable for the following potential applications:
i. High speed internet access where it is currently unavailable. So with WiMAX, everyone can access the internet by using their device.
ii. Substantially increase data speeds for applications to include online gaming, streaming video, video conferencing, VoIP and location based services. For older broadband, there were too slow compare to WiMAX. So that, to access any application such as video, must have a high speed to support the transfer rates.
iii. Drive wireless internet equipment without using any cables and its make more simply in a long distance.
Although, WiMAX had been used in a largely modern country and not in a world wide but it still in early phase and it is a new technology. In a modern country, WiMAX is quiet famous connectivity. There are several example of using WiMAX:
i. With a robust telecommunications infrastructure already in place in the U.S. Mobile WiMAX services from Sprint and Clearwire will reach more than 150 million consumers by year end 2008. On this statement shows that on WiMAX, it can connecting for all American people with is in a large country.
ii. In Australia, WiMAX technology will establish an affordable and efficient broadband network. This wireless broadband technology is perfectly suited for regional and rural areas and the purchase and installation process of WiMAX technology is faster, simpler and cheaper than other offered solutions. Additionally, the non-line-of-sight (NLoS) capability means that WiMAX technology can provide coverage despite the challenges of geography and the limited footprint of wire line.
iii. Taiwan has continued its leadership in the development and deployment of WiMAX operability with six commercial WiMAX licenses awarded in July 2007 for six separate Taiwanese wireless communication providers. In regions like Taiwan, where users are spread out and the wireless traffic is going a long distance, WiMAX technology provides a reliable, inexpensive solution for constant wireless broadband connectivity.
In Africa as a developing continent, WiMAX technology provides the opportunity to connect the African people with Internet and VOIP services faster and more affordably than wire line.
7.1 Access to the WiMAX Network Access to the Mobile WiMAX network is possible through a wide selection of devices and form factors which support varying degrees of mobility such as:
i. Indoor units, also called CPE or Customer Premise Equipment.
ii. Outdoor units which are mounted outside a building and use high-gain antennas.
iii. PC cards that fit into slots in a notebook/ laptop.
iv. Embedded WiMAX network modules integrated into a notebook / laptop.
v. Handhelds and PDA’s with WiMAX interfaces integrated on the system board.
7.2 WiMAX Applications
The WiMAX standard has been developed to address a wide range of applications, as summarized in the following table:
7.3 The Advantages and Disadvantages of WiMAX
The advantages of using WiMAX are included cost, coverage, capacity and standard for both fixed and mobile wireless usage models. There are:
i. Lower cost - A standards based platform for WiMAX technology drives down costs delivering volume economics to WiMAX equipment.
ii. Wider coverage - The technology behind WiMAX has been optimized to provide excellent non-line-of-sight (NLoS) coverage. NLoS advantages are coverage of wider areas, better predictability of coverage and lower cost as it means fewer base stations and backhaul, simple RF planning, shorter towers and faster CPE install times. WiMAX has a communication range of up to 30 miles. This can cover over 2800 square miles, ½ enough to blanket an entire city.
iii. Higher capacity - A key advantage of WiMAX technology is to use Orthogonal Frequency-Division Multiplexing (OFDM) over Edge, GPRS, HSPA to deliver higher bandwidth efficiency and therefore higher data throughput, with more than one Mbps downstream and higher data rates. Adaptive modulation also increases link reliability for carrier-class operation and the possibility to keep higher order modulation at wider distance extend full capacity over longer distances.
iv. Standard for all usage models (fixed to mobile) - By leveraging the same technology networks, WiMAX technology will become the most cost-effective solution for carriers to deploy for any usage model from fixed to mobile. The WiMAX Forum certifies products for conformance and interoperability based upon the standards IEEE 802.16.
v. Wireless - By using WiMAX system, companies no long have to rip up buildings or streets or lay down expensive cables.
Although WiMAX is a new technology broadband which is faster, higher bandwidth and wider coverage but still have weaknesses.
i. Line-of-sight is required for connections 5 mil or further. ii. Weather conditions like rain could interrupt the signal. It will be happen to all wireless connection. iii. Other wireless equipment could cause interference. iv. Multiplied frequencies are used.
v. WiMAX is very power intensive technology and requires strong electrical support. So, more electric power must be provided at the WiMAX base station. vi. Realities of WiMAX data rates are more like 72 Mbps and reduce as you add distance.
